Class ST_Contains

java.lang.Object

org.apache.hadoop.hive.ql.udf.generic.GenericUDF

oracle.spatial.hadoop.vector.hive.function.ST_Contains

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class ST_Contains
extends TwoGeoFunction

Determines if geometry1 contains geometry2, returning true or false.

Format:
 ST_Contains(geometry1 ST_Geometry, geometry2 ST_Geometry, tolerance NUMBER) - return true if geometry1 contains geometry2
  geometry1 has to be any polygon or any solid.
  The tolerance at which geometry2 is valid is optional.
  By default the tolerance is 0.05 for geodetic geometries and 0 for non geodetic.

Example:
 select ST_Contains(
  ST_Polygon('{"type": "Polygon","coordinates": [[[1, 2], [5, 2], [5, 6], [1, 6], [1, 2]]]}', 8307),
  ST_Point('{ "type": "Point", "coordinates": [2, 3]}', 8307)
 ) from hivetable LIMIT 1; -- return true
